IMPROVEMENT I Nf, COTTON-PRESSES.,

Specifica-tion forming part of LetterswPatcnt No. 198,907,` datedJanuary 11878; application filed d A i Ju 11e13,1`877. y v v countyoiFannin and State of TeXaS, have invented certain new and useflilImprovements in Cotton-Presses, of which the following a specification;`f. y u .y v This invention relates to certain improvements incotton-presses, its object ,being` to produce Va compact and efficient,apparatus,`

'adaptedto be secured in the iioor between the rst and second stories of`a building, in` such manner that .the `press-box can be filled andthevcotton `made -up` into bales in the upperV story, while the pressing`operation is effected from below. y y y y,

Our invention consists of a vertical rectangular box constructedv in twosections, the lower section of which is permanently secured at its upperend in a suitable opening in the I f iloor between two stories of abuilding, the upper section being formed with Vdetachable sides, andadapted to be clamped in position Vupon the lower section by means ofhinged straps at each side, which are pivoted at their lower ends tostraps passing downwardly under the bottom ofthe press and around abridgetree, which they support in place against the bottom, saidbridge-tree carrying a rotating internally screw-threaded sleeve,through which pa-sses a screw which actuates the follower, the sleevebeing put in operation by means of levers secured thereto, as more fullyhereinafter set forth. v,

Our invention further consists in a certain improved arrangement ofdevices'for elevating the crown-cap of the upper section to permitthecotton to be fed into the press, as more fully hereinafter specied.

` In the drawing, Figure 1 represents a vertical sectional `view of ourimproved press;

l Fig. 2, a side elevation thereof.

The letterA` represents the lower section of our improved press,consisting of a rectangular box, the sides of which are bolted togetherin any convenient manner, and strengthened by means of the timbers B B',mortised and clamped together around said section. The upper timbers,B', extend to the rear of the section, and form the base of an uprightframe,

l ftheobject of which will be more fully hereinafter explained. A 1 L vThe letter `l)l represents the upper section,

formed of detachable sides, strengthened by battens E E', two of the`upper battens, E, projecting beyond the sides, and lbeing provided withstaples F for the reception ofthe hooks G, by means of which the sidesare held together atthe tops, the lower endsof said sides sitting, wheniu place, within the timbers B', above the lower section of the press,and being heldin position V.by-,said timbers. .y lheletters'll Hrepresent two ilat straps,

secured attheirupper ends to twoof the timbers Bl` on opposite sides ofthe press', said straps passing below and under the box, being bent intoangular shape below the b o'x for `the reception of the bridge-tree 1the angular partof said straps lpassing around the angular braces t' ofsaid bridge-tree, and sitting within grooves in the bridge-tree toprevent displacement.` Through the lower horizontal block la of thebridge-tree passes an internally screw-threadedsleeve, L, the upper endof which is provided with a head Z, and the lower end with polygonal"sides l', for the' reception of the lever-block M, to which the leversN are secured.

The lever-block is provided with two oppositely-projecting arms, m, withrecesses on the upper sides,`in which the levers are secured by means ofbolts n passing through the levers, and secured in the lever-block.Through `the sleeve, and gearing therewith, passes a vertical screw,O,the upper end of which is rigidly attached to a follower, P, whichtravels in the lower section of the press.

The letter Q represents the crown-cap ofthe press, which lits upon theupper section thereof, and which may be confined thereon by means of thestraps R R, pivoted at their lower ends to the straps H H, secured tothe lower section of the press, said straps passing over the ends of thebatten S extending across v timbers B resting upon the upper surface ofthe floor, and the lower section projecting into the lowers-tory and theupper section in the upper story thereof. The press is lled with cottonfrom the top, the crown-cap being elevated for the purpose. Thecrown-cap is then secured in place, and the press put in operation frombelow, compressing the cotton into the upper section. When the bale isproperly formed and pressed the sides of the upper section may beremoved for the subsequent operations necessary for completing the'bale.

By the peculiar construction of the press,

and the method of clamping the crown-piece and bridgetree thereto, itwill be evident that the whole strain of the pressure will be upon themetallic straps passing under the machine and over the crown-cap, whichadds greatly to the strength and durability-of the press.

i What we claim, and desire to secure by Lety ters Patent, is-

1. The combination, in a cottonpress, ofthe upper and lower sections,the crown-cap and its elevating devices, the bridge -tree and straps,connecting the same with crown-cap, the'screw-threaded sleeve and itsscrew, and the follower traveling in the lower press-see tion, the wholeadapted to operate substantially as herein set forth.

2. In combination with the two parts of the press, the bridge-tree I,angular braces z' i, and lower horizontal block k, containing theinternally-threaded sleeve for operating the screw, of the straps H,passing around the horizontal block 7c', angular braces i, andbridge-tree I, and attached at their upper ends to the timbers B', andthe looped straps R R, pivoted at their lower ends to the straps H, andadaptedto hold the crown-cap down, substantially as described.

3. The combination, with the press, of the upper timbers B', projectingin rear of the press, the upright frame O, attached tothe rearwardextension, the beams T T, hinged to the frame O, and carrying thecrown-cap, the

pulley V, and the windlass W, carried by said frame and the rope orchain U, substantially as and for the purpose described. In testimonythat we claim the foregoing we have hereunto set our hands in thepresence of the'subscribingwitnesses.
